Special “chambers” containing small, round cells (arrows) or groups/clusters (asterisks) of these cells. The diameter of these small, round cells was up to 5 μm with nuclei filling almost the whole cell volumes. They were located among epithelial cells or just below them in ovarian sections of women with borderline ovarian cancer after hematoxylin-eosin (HE) staining (a-h). In the vicinity of these “chambers” the ovarian surface epithelium was drastically changed with several layers of proliferated epithelial cells, epithelial cells of atypical shapes (e.g., extended) and formation of papillae. (Light microscope, magnification 1000x). Red Bar: 100 μm
